In this paper, we take a first step in exploring the effect of xR devices on the experiences of users in the context of human-agent interactions. We report on the design and heuristic evaluation of an embodied conversational agent integrated into either a Virtual or Mixed Reality environment. Our evaluation with four experts show that Virtual Reality may elicit a better experience from users, while Mixed Reality may evoke a better sense of social presence due to natural user embodiment and spatial references to physical objects in the real environment.
